-277 RED SILICONE 70D O-RING

APG stocks the S70MD277, an AS568-277 red Silicone 70 Shore A O-Ring built to an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against many oxidizing chemicals, extreme heat and cold, and ozone and UV exposure. That behavior comes from the compound itself: Silicone delivers physiological inertness and low toxicity, an exceptionally wide service temperature range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving hydrocarbon fuels and oils or steam above its rated range call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across pharmaceutical manufacturing, ovens and heated equipment, and food and beverage processing.
